Full Answer

The oldest known sausage recipes utilized intestines from lamb and goats. Cow and pig intestines are made into casings as well. Traditionally, only a specific layer of the small intestine is used to make edible casings. This layer is called the sub-mucosa and is especially rich in collagen. Other parts of the intestine may be used to make non-edible natural casings. These include the large intestine and the small intestine, which does not have the muscular layer removed.

Artificial collagen casings are not made from sub-mucosal collagen but from highly processed hide and bones. Cellulose for sausage casings often comes from wood pulp and cotton producers. Plastic for casings is made via a similar process as other plastics.
